Here is a question for all you railroad watch enthusiasts, which I posed for the editors of the NAWCC Bulletin. There were several brands of wristwatches that carried the label "railroad approved" . Bulova Accutron, Ball, and Elgin's B W Raymond are some examples. I believe these watches were made in the 50's and 60's. The question is just when did the railroads approve wristwatches for time service and which watches. Also, were the requirements the same for wristwatches as were for the pocket watches? Where might information about railroad time service be found?
